The decorative frame 12 is attached to the instrument main body 11 by screwing screws into the mounting members 28 of the instrument main body 11 through the respective mounting holes 37 of the decorative frame 12.

When the decorative frame 12 is attached to the fixture body 11 in the first attachment orientation, the terminal block 43 is positioned on the end surface wiring hole 27a side, so that the electric wire drawn into the fixture body 11 from the end surface wiring hole 27a is drawn into the space in the lateral area facing the side surface on which the electric wire insertion hole 61 of the terminal block 43 is provided, and is bent and stored in a state connected to the terminal block 43.

The protrusion 56 that protrudes from the back side of the power source section 45 is arranged at the position of the escape hole 26 in the back surface 16 of the instrument main body 11, and is prevented from interfering with the instrument main body 11. That is, two protrusions 56a arranged in the transverse direction b are arranged in two relief holes 26a arranged in the transverse direction b, and one protrusion 56b shifted in the longitudinal direction a from the two protrusions 56a is arranged in the longitudinal direction a. is arranged in one of the escape holes 26b. The protrusion 56 is not arranged in the other relief hole 26c.

In addition, when the appliance main body 11 is installed by drawing an electric wire through the end side wiring hole 27b of the end plate portion 18b on the other end side, the electric wire drawn into the appliance main body 11 is inserted into the electric wire insertion hole 61 of the terminal block 43. Connecting. As shown in FIG. 4, the decorative frame 12 is oriented in the longitudinal direction with respect to the first mounting direction so that the terminal block 43 is disposed on the end side wiring hole 27b side of the end plate portion 18b on the other end side. It is assembled on the front side of the instrument main body 11 in the second mounting orientation rotated by 180 degrees.

With this combination, the second heat sink part 49 of the heat sink 41 protruding from the back side of the decorative frame 12, the power supply part 45 of the light source unit 42, and the terminal block 43 are inserted into the inside of the appliance body 11, and the appliance body The mounting base portion 29 of the mounting member 28 protruding from the front side of the decorative frame 11 is inserted into the inside of the decorative frame 12.

Screws are inserted through each mounting hole 37 of the decorative frame 12 into the mounting members 28 of the instrument body 11, and the decorative frame 12 is attached to the instrument body 11.

By attaching the decorative frame 12 to the device main body 11 in the second mounting direction, the terminal block 43 is arranged on the end side wiring hole 27b side, so that the electric wires drawn into the device main body 11 from the end side wiring hole 27b are is drawn into a space in a side area opposite to the side surface of the terminal block 43 where the wire insertion hole 61 is provided, and is bent and accommodated in a state connected to the terminal block 43.

The protrusion 56 that protrudes from the back side of the power source section 45 is arranged at the position of the escape hole 26 in the back surface 16 of the instrument main body 11, and is prevented from interfering with the instrument main body 11. That is, two protrusions 56a arranged in the transverse direction b are arranged in two relief holes 26a arranged in the transverse direction b, and one protrusion 56b shifted in the longitudinal direction a from the two protrusions 56a is arranged in the longitudinal direction a. is arranged in the other relief hole 26c. The protrusion 56 is not arranged in one of the escape holes 26b.

Then, when emergency power is supplied from the emergency power supply device to the lighting device 10 through the electric wire, the power supply section 45 converts the emergency power into predetermined lighting power and supplies it to the light source module 51. The light source module 51 to which lighting power has been supplied lights up, and the light is emitted through the lens 53.

In addition, the heat generated by the light source module 51 when it is turned on is transferred to the heat sink 41, from which it is dissipated into the air.

In the lighting device 10 configured as described above, the light source unit 42 and the terminal block 43 are integrally arranged in the decorative frame 12 by the heat sink 41, so that it is difficult to connect electric wires to the terminal block 43 and assemble it. Makes work easier.

The light source unit 42 and terminal block 43 are arranged side by side in the longitudinal direction a of the decorative frame 12, allowing the components to be arranged by effectively utilizing the limited space within the fixture.

The terminal block 43 is offset to one side in the short direction b of the decorative frame 12, and the decorative frame 12 can be rotated 180° in the longitudinal direction a to be attached to the fixture body 11, so that the terminal block 43 can be positioned in an appropriate position to connect the electric wires regardless of whether the electric wires are pulled in from the back side, one end face side, or the other end face side of the fixture body 11.

Since the terminal block 43 has a wire insertion hole 61 on the side surface opposite to the direction offset to one side of the transverse direction b, the space on the opposite side to the offset direction can be utilized for wire wiring work. In addition, since the connection direction to the terminal block 43 is in a direction that intersects the direction in which the wires are pulled out from the back side or end side of the device body 11, the wires can be easily pulled out from the terminal block 43. It can be made difficult.

The wire insertion hole 61 of the terminal block 43 is positioned outside the rear side of the decorative frame 12, making it easy to insert and connect the wire into the wire insertion hole 61.

In the rear view of the device main body 11, the terminal block 43 and the back side wiring hole 25 are arranged side by side in the short direction b of the device main body 11, so that the electric wire drawn from the back side wiring hole 25 cannot be bent. It is possible to connect the wire to the terminal block 43 by bending the wire, thereby ensuring a space for bending the wire.

Furthermore, even when the light source unit 42 has the protruding part 56 that protrudes from the back side, by providing the relief hole 26 in which the protruding part 56 is arranged in the back part 16 of the appliance main body 11, the decorative frame 12 can be attached to the appliance main body 11. During installation, the protrusion 56 can be prevented from hitting the back surface 16 and interfering with assembly.

When the decorative frame 12 is attached to the fixture body 11, the rear side of the light source unit 42 may be configured to engage with the rear portion 16 of the fixture body 11, and the light source unit 42 may be configured to be sandwiched and held between the fixture body 11 and the decorative frame 12. In this case, even if the decorative frame 12 is attached to the fixture body 11 with the orientation of the longitudinal direction a rotated 180°, the rear side of the light source unit 42 is configured to engage with the rear portion 16 of the fixture body 11.

Although several embodiments of the invention have been described, these embodiments are presented by way of example and are not intended to limit the scope of the invention. These novel embodiments can be implemented in various other forms, and various omissions, substitutions, and changes can be made without departing from the gist of the invention.
